Chapter 1 Introduction This manual contains information needed for Levels One and Two radio servicing. Level One servicing consists of radio programming, radio alignment, knobs replacement, and installation and removal of the antenna, belt clip, battery, and universal connector cover. Level Two servicing covers disassembly and reassembly of the radio to replace circuit boards.

In order to avoid operating outside the limits set by the FCC, we recommend that you align the ASTRO APX 5000/ APX 6000/ APX 6000Li radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first. Checking this parameter when the product is placed in service is especially important if the product has been in storage for a significant period of time (6 months or more) between being shipped from the factory and commissioned for service.

Never poke this vent with any objects, such as needles, tweezers, or screwdrivers. This could create a leak path into the radio and, in the case of APX 5000 R/ APX 6000 R radios, the radio’s submergibility will be lost.

Sec 2: 8-42 Disassembly/Reassembly Procedures: Ensuring Radio Submergibility 8.10.7.1 Vacuum Tool Setup 1. Attach one end of the hose to the Vacuum Pump. Attach the other side of the hose to the Vacuum Adapter. 2. Tool Leak Test: Block the open end of the Vacuum Adapter. Pull the knob on the Vacuum Pump to create vacuum.

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility Sec 2: 8-43 8.10.8 Pressure Test (using NTN4265_) Pressure testing the radio is necessary only if the radio has failed the vacuum test. Do not perform the pressure test until the vacuum test has been completed. Pressure testing involves creating a positive pressure condition inside the radio, submerging the radio in water, and observing the radio for a stream of bubbles (leak).

Sec 2: 8-44 Disassembly/Reassembly Procedures: Ensuring Radio Submergibility • Main Chassis, including the Control Top • Back Chassis 8. Remove the radio from the water container and dry the radio thoroughly. Be especially careful to dry the area around the Vacuum Port and the battery contacts area. To avoid equipment damage, keep the area inside the Battery contact pocket is dry before assembling battery.
